30 Appendix E: Installation of Missing Generic Netlink Libraries

libnl CFlags should be enabled with CONFIG_LIBNL32=y in supplicant and hostpad .config file \[The above

configuration settings should be set to "y" in case NL80211 is used\]. Make sure that the NL80211 support and

Hostapd support are enabled in the menuconfig during compilation.

Create a directory in the location where Tool chain and BSP are present

mkdir build

Download the libnl 3.2.xx.tar.gz\[Referring 3.2.27.tar.gz as an example here \] library and extract it in the build directory.

cd build

tar xvf 3.2.27.tar.gz

Configure the libnl library for target platfrom

CC=/path to the toochain/bin/arm-linux-gnueabihf-gcc

./configure --host=arm-linux-gnueabihf -prefix=/<complete path to build directory>/

Here headers will be installed in ${prefix}/include/libnl3.

Make and install the libraries in the destination directory or else they will be installed in /usr/local/lib and

/usr/local/include/libnl folders of host machine by default.

Follow the example given below:

make DESTDIR=$(arm-cortex_a8-linux-gnueabihf-gcc -print -/<path to build

directory>/build/)

Exporting the path for build directory in the command line or add these flags in the supplicant and hostapd config files

under CONFIG_DRIVER_NL80211= y variable.

#export LDFLAGS='-L/<path to build directory>/lib/libnl'

CFLAGS += -I/<path to build directory>/include/libnl3

Ex: LIBS += -L/<path to build directory>/lib/libnl

LIBS : Contains a list of additional libraries to pass to the linker command.
